Abstract
A receiver circuit receives an incoming signal and accordingly provides an internal signal, and includes an equalizer, a slicer module and a counter module. The equalizer provides a signal level according to the incoming signal, the slicer module compares if the internal signal exceeds a level range; according to comparison result, the counter module provides a signal quality indication capable of indicating whether a bit error rate of signal receiving is greater than a predetermined reference bit error rate. One of an upper bound and a lower bound of the level range can equal the signal level, a distance between the upper bound and the lower bound is set according to a reference signal-to-noise ratio which associates with the reference bit error rate.
